Sir , After i proceed with your hint,

i mean after i change the code like

foreach (System.Collections.Generic.List<GMap.NET.Point> tilePoint in Core.tileDrawingList)

its giving me a Error like

[Error 1 Cannot convert type 'GMap.NET.Point' to 'System.Collections.Generic.List<GMap.NET.Point>'
]

Hi there,

tileDrawingList returns a List<GMap.NET.Point>, so each item in the list is a GMap.NET.Point, not a List<GMap.NET.Point> itself. So instead of var, use GMap.NET.Point.

Good Morning Sir,

now am facing another trouble with .net 2

if(opt.Contains("http://"))

its trigger a error as

Error 1 'string' does not contain a definition for 'Contains)

what the error might be?

Hi there,

string.Contains is not supported in the Compact Framework 2.0. To check out this stuff for other problems you run into, first take a look at the MSDN documentation:

http://msdn.microsoft.com/en-US/libr...(v=VS.80).aspx

Each member supported by CF has a tiny mobile icon. For Contains, there's none. Then Google will tell you what to do next:

The trick is to use IndexOf instead which returns -1 when the string is not found.

Cheers,

opt.IndexOf ("http://")

Error 1 Cannot implicitly convert type 'int' to 'bool'

this is the error am getting while using indexof in coding Sir?

Take another look at the MSDN documentation I linked to; IndexOf returns in integer (-1 when the string is not found), and not a bool as Contains does....
